The Purpose of Flashings: Flashings are essential for the correct installation of roof windows. Precisely designed flashing details ensure a durable and neat fit with the roofing material used. The purpose of flashing is to ensure good drainage away from the window and to provide protection from the elements. As there are many roofing materials available, Fakro offers a range of flashing solutions. Types of Flashing: Fakro roof window flashings are categorised according to roof material and application. Standard flashings are intended for the most common types of roof covering; flat-Flashing ES, profiled-Flashing EZ, and for roof surfaces with a high profile - Flashing EH. Roof windows can be installed in the roof structure at three different levels: N(3cm), V(0cm) and J(-3cm). Flashings are categorised accordingly. The last letter of the flashing type code indicates the depth at which the roof window can be fitted. For example flashing EZV means: E “ flashing. Z “ types of the roofing material. V “ level of installation. Note: All flashings are manufactured using aluminum as standard, permanently protected with a polyester varnish. The standard colour is brown RAL 7022, which matches well with most roofing finishes.
